DIVIDING AND BANDIE'G MACHINE.

Specification of Letters Patent.

Patented Aug. 23, 1910.

Application filed April 8, 1910. Serial No. 554,245.

To all whom 'it may concern:

Be it known that I, Auous'r G. BAUER, a citizen of the United States,residing at Columbus, in the county of Franklin and State of Ohio, haveinvented certain new and useful Improvements in Dividing and BandingMachines, of which the following is a specification.

My invention relates to the. improvement of dividing and bandingmachines of that class which are particularly adapted for use infacilitating the decoration of china plates or other disks, and theobjects of my invention are to provide a device of this class wherein iscombined improved means for dividing the surface of a plate or disk intouniform spaces through the production of radial lines, cords, circlesand other divisional indications thereon.

A further object of my invention consists in providing improved meansfor supporting a plate against undesirable rotation or movement and forcentering the plate upon the supporting drum.

1 These objects I accomplish in the manner illustrated in theaccompanying drawing, in which- Figure 1 is a plan view of my device,Fig.'

2 is a side elevation thereof, Fig. 3 1s a sectional view on line 33 ofFig. 1, and, Fig. 4 is a detail section on line 44 of Fig. 1.

Similar numerals refer to similar parts throughout the several views.

In carrying out my invention, I employ a supporting frame which consistsin a horizontal member 1 from the forward end portion of which rises atubular standard 2 and from the base of which extends radially adesirable number of supporting legs 3. About the tubular standard 2 isprovided a horizontally disposed drum 4, the top member of which isformed on its underside with a central downwardly extending bearing pin5, this pin extending within the central socket or opening of thetubular member 2. The weight of the drum, however, is supported bybearing balls 7 which are arranged in a circular cage 8 between theenlarged head of the pin and the upper end of the tubular member 2,these balls having their upper sides in contact with the underside ofsaid pin head enlargement and having their lower sides in contact withthe upper end of the tubular standard 2.

In the construction of the drum 4, I provide the otherwise flat upperface thereof, with a plurality of circular grooves 9 which are struckfrom the center of the drum head. Through the upper side of the drum,are formed radial lines of vertical pin holes or sockets 10, thesesockets being arranged to intersect the grooves 9.

In the outer end of one of the legs or base frame arms 3, is supportedthe lower end of an upright post or bar 11, the latter having formedtherethrough a vertical line of equidistant pin openings 12 either oneof which is adapted to receive the stem of a suitable pin 13. Throughthe vertical cylindrical wall of the drum 4 are formed straight, curvedand inclined lines of pin openings or sockets 14, which openings are inhorizontal alinement with the pin openings 12 of the post 11. Theopenings 14 are so arranged with reference to each other, that thedistances between all of those openings which are of equal height fromthe bottom of the drum, represent equal divisions of the circumferenceof the drum. For example, the space or distance between any two of thehighest openings 14 on the drum, is equal to one-third of thecircumference of the drum, while the next lower horizontal row ofopenings 14, divide the circumference into fourths and the loweropenings near the bottom of the drum, divide the circumference of saiddrum into sixteenths.

Upon the outer end of the frame member 1, is pivoted the vertical pinextension 15, which depends from one end of a horizontal bar 15 in theouter or remaining end of which is pivoted the vertical pin termination16 of an upright standard 17 This standard is adapted to be rotated tothe desired position and held in such position through the medium of aset screw 18, which passes through a threaded opening in the outer endof the bar 15, while a similar set screw 19 in a like manner, passesthrough the outer end portion of the frame member 1 and engages the pin15. The standard 17 has slidably connected therewith, the outerhookshaped end of a horizontal arm or bar 20, which is adapted, as shownin the drawing, to extend over a portion of the upper side of the drum4. This arm is held at its desired height on the standard 17 by a setscrew 21. Adjacent to the periphery or on the outer marginal portion ofthe horizontal drum top, I provide upwardly projecting I side or face ofthe arm three eqnal spaces.

- 5 post 11, the pin is pins 22, these pins being arranged diametricallyopposite each other and being connected by rubber bands 23, which areunder tension, said bands crossing each other at the center of the drumtop.

In utilizing my improved device for dividing a plate into desirabledivisions or spaces, the plate is supported centrally upon the drum andupon the crossed rubber bands 23, and in order to insure the retentionof the plate in its central position, retaining pins, are inserted inthe corresponding pin holes 10, these pins contacting with the edge ofthe plate and insuring its central support on the drum. Owing tothe factthat the plate rests upon the rubber bands, any tendency of the plate torotate upon the drum, 1s obviated.

It will be observed that for the production of radial lines on theplate, the arm 20 and itsgsupports are so set as to cause said arm toextend radially over the upper side of the drum and beyond the centerthereof, one being substantially inalinement with the drum center andplate center. Wewill assume that it is desired to produce upon theplate, radial lines whereby the face of the plate, will be divided intoIn order to attain such a division, the pin 13 which is supported in theupper opening 12 of the post 11, is drawn out of engagement with anupper drum opening sufliciently to permit a rotation of the drum. 7 Whenthedrum has been manually moved-or-rotated until the pin 13 is oppositethe next succeeding opening 14: which is of corresponding height on thedrum with that occupied by the pin in the pressed into said opening 14;to temporarily lock the drum against further movement. third of acompletev rotation of the drum, has been attained and'at the beginningand ending of this operation, radial lines are center of the plate tothe drawnfrom the outer margin thereof by means of a pencil which isheld, upright and in contact With onefface of the guide arm 20. By thussuccessively withdrawingthe pin 13. and inserting the same in the upperopenings, as the drum is. revolved and: utilizing the arm 20 asastraight edge, it will be understood that the; upper face of the platewill be divided by the-pencil lines intothree equal divisions.Byutilizing} the next lower set of pin holes 1'4: for the reception ofthe pin 13, it is obvious that thesurfaceof the plate may be dividedintofourths and in a. like manner other-divisions of theplate may be made bythe insertion of theopenings.

Itis-obviousthat the ingcircles on thepin 13 into said lower operationof producplate or of impartinga j marginalba-nd, thereto, may beaccomplished by holding a brush vertically against the shown anddescribed ,cumference of said from the frame adjacent to the peripheryof the body and having openings therein in horizontal alinement with thepin holes in said body, and an arm connected with said standar 5 andextending above said rotatable body- Bythis operation, one- 5 thecombination with r circular rotatable body mounted thereon and providedwith lines holes, there being circles formed on the upper face of saidrotatable body, and means arm 20 at the desired point. It will also beunderstood that by swinging the arm 20' and its standard 17, the arm maybe made to extendover portions of the drum at different angles, thusadmitting of the production of lines in different directions on theplate and aiding in the production of certain desirable designs thereon.This movement of the arm 20 for the purpose of producing cord lines onthe plate and other design lines, is facilitated by the employment ofthe bar 15 which may be swung to such position as to admit of adesirable intersection of the arm 20 with the circle described by thedrum.

From the foregoing description, it will be seen that simple andeflicient means areherein provided for accomplishing the obj ects of theinvention but while the elements are well adapted to serve the purposesfor which they are intended, it is to be understood that the inventionis not limited to the precise construction set forth, but

includes within its purview such changes as may be made within the scopeof the appended claims.
